Given: -

Number of animals in a national park by the end of December 2020 was

= 2560

Percentage of animals increases every year = 60%

We need to find the number of animals were in the national park by the end of November 2020.

Now,

According to the question,

We get this equation: -

x + 60% of x = 2560

Therefore,

$x+60x/100 = 2560\\100x+60x/100=2560\\160x/100=2560\\160x=2560*100\\x=256000/160\\x=1600$

Therefore,

The number of animals were in the national park by the end of November 2020 = x = 1600
